Grab an Arduino jar and weigh it empty. Then fill the Arduino jar up with the river water and weigh it again. After that use the Arduino water heater to evaporate all of the water. Using your Arduino scale measure the weight without water. There should be a delta weight. The new weight is how much not water is in the jar. Next using the Arduino furnace raise the temp to burn off non plant organics. Weight it again. That's how much bacteria was in the jar. To finish though you have to once again use your Arduino kiln to melt all of it and measure the gas chromographies flying out with your Arduinichrome. What's left is Corona.
